Unmanaged usb powered switch connection, port down but works

Bugs
1

This may be a Linux driver bug but posting here just in case.

I have one of these https://www.amazon.com/dp/B0CLP48WCL?psc=1&ref=ppx_yo2ov_dt_b_product_details connected to eth0 on my Vyos router.

My Vyos router is: https://www.amazon.com/dp/B0CG8J39FX?psc=1&ref=ppx_yo2ov_dt_b_product_details

It has 6 Intel i226-V NICs. With that un-managed switch connected to eth0, it passes traffic but Vyos/Linux reports eth0 as down.

This is the eth0 config:

ethernet eth0 {
         disable-flow-control
         duplex auto
         hw-id <mac>
         ipv6 {
             address {
                 no-default-link-local
             }
         }
         ring-buffer {
             rx 4096
             tx 4096
         }
         speed auto
     }

Use the same config for all NICs, except for the Inet NIC.

Last message in kernel log is:
br0: port 1(eth0) entered disabled state
Ports 0 through 4 are bridged.

Ethtool output:

Again, prob an underlying Linux bug.
